The storage battery - the general information, recommendations about service

General information

The 12-voltny battery established on the car consists from six banok in which positive and negative plates (ламели), shipped in solution of sulfuric acid are placed. The main task of the battery is production of the current necessary for осуществлениязапуска of the engine, ignition/activation of candles of an incandescence, lighting, and also for providing with a food of other onboard and auxiliary consumers of the electric power.

Absolute return of the battery takes place at ambient temperature 27°С. At - 18°С efficiency of return falls to 40 % and implementation of start of the engine needs in two with small time more energy.

The starting capacity (starting current) shows ability of the accumulator to start the car in the conditions of cold weather. It shows a current in amperes which gives the accumulator within 30 seconds at - 18°С without power failure below level in 7.2 In (the minimum level demanded for reliable start of the engine). The this indicator, the more starting capacity of the accumulator is higher.

The reserve capacity shows time in minutes during which the accumulator gives a current force 25 And at temperature 27°С, i.e. time during which the accumulator ensures functioning of all auxiliary devices in the car at night and in the conditions of limited visibility at the faulty generator.

In winter conditions, at temperatures below - 18°С efficiency of additional charge of the battery decreases in view of increase of internal resistance. At short trips in the winter the energy spent by the battery for start of the engine, does not manage to be restored, the battery begins works very hard, being gradually discharged and, eventually, fails is irreversible.

In summer months at long trips the engine strongly heats up, and often happens that it is difficult for starting anew. Not less energy is sometimes spent for such "hot" starts, than in frosty weather. Told in a special measure treats vysokokompressionny engines with large working volume of cylinders, and also to the models equipped with central air of air.

Removal and installation

Acquisition of the new storage battery

Told points to importance of correctness of a choice of the storage battery taking into account parameters of the engine and a vehicle complete set above.

The first, on what it is necessary to pay attention upon purchase of the new storage battery, these are its performance data. Such characteristics three.
The first: RATED TARGET VOLTAGE which has identical value (12 In) for all batteries applied on cars that practically excludes probability of a mistake.

The second: The CAPACITY measured in Ampere-hours (Аh or Ach) and, roughly speaking, defining a stock of the electric power containing in the battery. On a choice of size of this parameter depends, as long the battery will be capable to provide possibility of a provorachivaniye of the engine with a starter, is more exact - how many it is possible to make attempts of start of the engine.

And third characteristic: The STARTING CURRENT measured in Amperes (And), i.e. a current submitted on a starter at start of the engine. The size of a starting current on batteries can be specified on four various standards: GOST (for domestic accumulators), EN (a standard of Incorporated Europe), SAE (the American standard) and DIN (Germany). The last, German standard, is closest to the Russian state standard specification and on the majority of batteries of the European production is put down "by default" i.e. when the system of a standard is not specified. The starting current is higher, the big turns are developed by a starter and to those it is capable to transfer a bigger torque to an engine flywheel.

In an ideal, the acquired replaceable battery on the performance data should correspond completely to the requirements specified in the maintenance instruction of the car, at which observance term of its service to the maximum. Hardly it is possible to consider acquisition of the battery of smaller capacity as good economy of money as it will serve much less and, besides, can be at the bottom of the troubles connected with start of the engine in a winter season. It is not necessary to get also the battery schrezmerno a big starting current, - such increase is interfaced with рискомвыхода out of operation a starter. If the standard battery does not provide a due provorachivaniye of the engine, it will be more correct to make for a start replacement of impellent oil, - that it is rather всегоприведет to automatic elimination of a problem.

Lately the market of the country is overflowed with the poor-quality goods and fakes. Storage batteries also are not an exception. There are some signs on which it is possible with sufficient degree of probability to distinguish the original from a fake.
The first and, perhaps, main thing: on the case of the battery the country manufacturer and manufacturing plant should be surely specified, it is better, if with the address.
The second: the date of issue should be specified that special value has for batteries of tight (unattended) type. The delivery set by all means should include technical data sheet while existence of the instruction is not strictly obligatory that is connected with that in the West storage batteries practically do not arrive in retail, and their installation on the car usually is carried out by specialists of car-care center.
The third: high-quality batteries differ good appearance. The case should have equal edges, to be equipped with reliable jams and the smooth, covered protective caps polar plugs which are quite often processed by special anticorrosive greasing.

Battery charging

The charging of the failed battery should be made according to instructions of manufacturers of the charger.
